The current primary project I'm working on is actually quite similar to Gravid Gauntlet, just more expanded. Some could even consider it an update in and of itself. There are also a lot of fundamental changes involved, which could be a positive or negative depending on the individual. I'm hoping to get the initial release on Itch before the year ends. I've been project hopping for quite a bit to determine what I should do next, and this latest project was one I've had in mind before even Gravid Gauntlet. In fact, the prototype of GG was based off this earlier idea until towards the end of the production phase.
Now that I've returned to this older idea there's a lot I want to do with it. Pregnancy, of course, is planned, but I've been considering some other kinky implementations as well. It will also allow the player to "upgrade" their base between invasions, and also have other battles on different maps for resources and such. A larger cast is also planned with more interactions available for characters.
Thank you for your questions! It delights me to see that there is still people interested in my dumpster fire of a GameJam entry. I do hope this new game can be even more to your liking (specifically in regards to difficulty). I'm not sure how much more info about it I should disclose at the moment, considering how much of it is susceptible to change, but perhaps I can answer any other questions you have should you choose to ask them.
